The nature of my invention consists, first, in the novel construction of a frame for a harvester, geared with a spur master-wheel and first pinion and bevel second wheel'and pinion, said frame consisting of a metallic baseplate, having a standard cast at one end for the crank-journal of the crank-shaft, and a two-part cavity for the gearing cast at one side, said cavity-being'either cast complete, or having its outer side formed of sheet metal, and having in one part of it the master-wheel and pinion, and in the other part the second wheel and pinion, the whole frame being so arranged as that all the bearings for the journals of the gear-shafts shall be cast with the casting of which the base-plate forms a part, and being so combined with suitable covers and plates as to completely incase the gearing and protect the same from dirt or injury; secondly, in the construction of the hub of the driving-wheel, with ratchet-teeth formed on its interior at such distances from each other as to leave from one-fourth to one-half of its interior cylindrical surface between said teeth, which detached portions of the inner-hub sur face have a bearing on the face of a pawlwheel secured on the driving-shaft, and thus form an additional journal-bearing between the driving-wheel and shaft, thus increasing the solidity of bearing between the wheel and shaft, and lessening the liability of splitting the hub-box by a violent vertical or lateral crossstrain on the driving-wheel; thirdly, in hanging the finger-bar to the main frame by means of' a coupling-frame, consisting of a brace-bar and coupling-bar arranged diagonally on each other, and having one hingejoint at each end of the heel-shoe, a rolling hinge-joint at onepoint on the main frame, and a sliding pivot-joint at a second point on the main frame, said rolling hinge-joint and sliding'pivotjoint being both located between the planes of the driving-wheels, the object being'to obtain a rolling motion of the fingerbar without dispensing with the long rigid hinge-joint between the finger-bar and coupling-frame, which is the strongest and most durable construction for that connection, or without bringing either point of attachment between the main and coupling frames outside of the driving-wheels, by which the liability to side draft is diminished and a more compact construction is obtained; fourthly, in forming a coupling'frame for a harvester of a single bar of metal, so bent as to form the coupling-bar connection between the couplin g-bar and bracebar, which brace-bar crosses the coupling-bar, and is secured to it at said crossing, whereby I obtain a coupling-frame which is cheaply constructed, and is very light, stiff", and rigid; fifthly, in forming the heel-shoe of the fingerbar of a harvester of a plate of sheet metal, turned up at each end, and having'combined with it suitable cast pieces to form, with the upturned ends of the plate, sockets for the hinge-arms of the coupling-frame, whereby I obtain a shoe having a wrought-metal base, which insures the proper strength without the necessity of forming the hinge-sockets of wrought metal, thus lessening the weight and expense without impairing the utility of the shoe; siXthly, in the combination of mechanism for enabling the driver to throw the machine in gear by placing his foot on a treadlearm on the main frame, and to cause the machine to throw itself out of gear when not held or locked in gear by the driver, by which the danger of injuring or killing the driver, in case he is thrown from the machine in front of the knives, is materially diminished; seventhly, in the construction of a coiled-wire handle on the end of the wire attached to the pawl on the lever which raises the couplingframe, said handle being formed by coiling the pawl-wire around the lever in a coiled-spring form, the object being to obtain a cheap and simple handle by which the driver can operate both the lever and pawl with one hand; eighthly, in the construction of a crank-screw with a tapering or conical-threaded portion for securing the swinging end of the pivoted hinge-arm of the coupling-frame, the object being to obtain a screw which could be easily taken out by the driver whenever he desired to swing around the finger-bar, and which could as readily be secured so firmly in its hole as to prevent the possibility of its working loose and dropping out.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The general construction of the machineframe is shown in Figs. 15, 16, and 17, in which A represents the base-plate of the machine; G, the standard for the crank-journal of the pitman-shaft, which is cast with the base-plate A; and H I, the two-part cavity, which is either cast complete with the plate A, or it may be cast with said plate without the side J, which is then formed of sheet metal, and fits in a groove, 53, formed around the outer edge of the part H of the cavity, as shown in Fig. 15.

The side board 4-is cast on the side of the plate A, opposite the cavity H I, and serves as a strengthening-flange to that side of the frame, and the bearings 1 1 are cast in the plate A for the main shaft B. (See Fig. 1.)

The bearings 2 2 for the second shaft 36 (see Fi 6) are formed in the part I of the cavity, and the bearings 3 3 for the crankshaft 5 (see Fig. 6) are formed in the cavity I and standard G, as shown.

The cast cover D (see Figs. 1 and 2) fits over the part H of the cavity, and is secured by screws or bolts 54 54, and the sliding plate 15 covers the part I of the cavity, and is secured in position by sliding it under the flange 55 ot' the cover D, and a flange, 56, on the plate A, as shown in Fig. 1; or, if preferred, this cover E might be arranged as a hinged instead of a sliding cover, and could be hinged to the cover D or the plate A in a manner readily seen.

In the frame represented in Fig. 15 a slot, 57, is cast across the plate A, in order to allow of the main shaft B being placed on the frame A from above the frame, and a plate, 51, (shown in detached view) is used to cover the main shaft; but, if preferred, the bearings .l 1 could be cast on the lower side of plate A,

as shown in Fig. 6, when the shaftB would be put in position from below the frame A, in which case the use of the sheet-metal plate J becomes essential, in order to allow of the master-wheel being keyed on the shaft. 7

It is evident from this description that all the bearings 1 1, 2 2, 3 3 are cast on the same casting, of which the plate A forms a part; consequently there can be no derangement of the alignment of the bearings when once fitted; and it is also readily seen that all the gearing is incased in-the two-part cavity H I, the master-wheel and first pinion being incased in the part H and under the cover D, and the bevel-wheel and pinion being incased in the part I and under the cover E, thus completely inclosing the gearing from dust and dirt.

The particular arrangement of the several parts of the f time can be varied to suit different plans of constructionas, for example, the frame may be constructed for a front-cut machine, as shown in Fig. 15, or for a reareut machine, as shown in Figs. 1 and 5 or Fi 18; or the part I of the gear-cavity could be enlarged by the part K, as shown in Figs. 18 to 20, to allow of the introduction of the two-speed bevel-gear, (shown in Fig. 18;) or the part H could be made of sufficient width to allow of the use of the double-cogged master-wheel, which would act in combination with changeable pinions on the second shaft to produce different speed, the general plan of construction being the same in all cases.

The mainshaft B is secured in the bearings 1 1 by suitable covers, and has the drivingwheels (3 C at its ends, as shown.

The hub 15 of the wheels 0 is made in a box form, as shown in Figs. 9, the back face ex tending out into a long axle-box, as shown in Figs. 1 and 2, and the front being covered by the cover 14, (shown in Figs. 9,) which is secured to the hub-box by screws, and forms the outer end of the axle-box, as shown in Figs. 1 and 2.

The pawl-wheel 16 is keyed on the shaft B, and is made with a flat face of the same diameter as that of the interior of the hub-box 1.5.

The notch 59 is cut in the face of the wheel 16, and has a circular hole, 60, formed at the end; and the pawl 18 is made with a cylindrical end, 17 and is secured in position by sliding the end 17 into the hole 60, as is readily seen.

The spring 19, which keeps the pawl 18 forced forward, is simply a spiral spring placed in a hole in the wheel 16 under the pawl.

On the inner face of the hub-box 15 are cut the ratchet-notches 20 20, which are of such form and at such distances from each other as to leave the bearing-faces 21 21 between them nearly or quite as long as the notches themselves, from which it is evident that nearly or quite one-half of the inner face of the hub-box is left to give the wheel a journalbearing on the face of the pawl-wheel 16, so that the driving-wheel has in effect a solid journal-bearing from .one end of the hub to the other, by which the danger of the wheelbearing wearing loose and allowing the wheel to wabble, as well as the liability of splitting the hub-box by a sudden side lurch of the machine, is materially lessened.

The master-wheel 41 (see Fig.8) is keyed on the main shaft B, and meshes into the first pinion 33, which is free to revolve and slide on the second shaft 36.

The grooved clutch 34 is formed on the inner face of the pinion 33, and the circular groove 48 is formed in the outer face of said pinion, in which groove is placed the spiral spring 50, which presses on the washer 49, secured on the shaft 36, and keeps the pinion 33 clutched with the clutch 35 on the shaft 36.

The lever 37 is pivoted to a lug, 38, on the cover of the bearing 2, and has an end bearing on the lever 40, which is made forked at the lower end, and fits in the groove in the clutch 34 on the pinion 33, and is pivoted to a lug, 42, on the flange or cover 1), as shown in Fig. 8.

The rod 39 is attached tolever 37, and passes up through flangeof cover D to the end of the lever 43, (see Fig. 6,) which is pivoted at side of cover 1), and has the treadle-arm 45 (see Fig. 2) at the other end.

The spring 44is secured on the cover D,and presses down on the lever 43 with sufficient force to force down the rod 39 and lever 37 when the treadle end of lever 43 is free, and thus forces back the lever 40 and pinion 33, so as to throw the machine out of gear.

The driver in his seat can place his foot on the treadle-arm 45 and throw the machine in gear, and, by means of the button' 46, can

fasten the lever 43 down to hold the machine in gear, the button 46 being thrown back on the pin 47 when not in use. 1

The coupling-frame for a rear-cut machine (shown in Figs. 1., 2, 5, and 13) consists of a single bar of metal, L N M, which is bent in the form shown, so as to form the couplingbar 'L, eye K, cross-piece N, and brace-bar M, the bars L and 11 1 crossing each other, as shown, and being united by the clampingpiece 1 and brace-plate 0, with accompanying rivets at said crossing, and the ends -of said bars being united by the rod Q, which rod serves as thehinge-pin for the rolling bolt R on the couplingbar, and for the pivot-pin for the tilting end of the coupling-frame at the end of the brace-bar M. WVhere a runner is used for the coupling-frame, the cross-bar N is formed under the plane of the bars M L, as shown in Fig. 13, and the runner j is secured to itby bolts m m, as shown in Figs. 14; but where a wheel is used at the heel of the finger-bar, the cross-bar N is formed above the bars M L, as shown in Fig. 10, to avoid unnecessary friction.

The rolling bolt R is secured in the lug 24 on the standard G of the machine-frame, (see Fig. 6,) and the end of rod Q is journaled in the block 26, which slides up and down in the slide-box 25, which is secured by arms 31 32 to the part I of machine-frame.

The stirrup 32 is pivoted to a collar, 27, journaled on the rod Q back of the brace-bar M. and its end is pivoted on the crank 28 of the rock-shaft 30, which is secured in boxes 29 29 on the frame-plate A. The lever 9 fits in a hole in the rock-shaft 30 in such a manner as to have some lateral movement, and extends up through a slot in the plate A to the side of the drivers seat. A spring, 52, (see Fig. 1) is secured to the side plate 4, and lies over the lever 9, so as to keep it pressed up to said side plate, by which a pin on the inner face of said lever is caused to enter one of the holes 63 in the side plate 4, (see Fig. 5,) and the lever is held in position.

From this description it is evident that the driver, by operating the lever 9, can raise or lower the front end of the coupling-frame to suit the angle required between the fingers and the ground, the rolling bolt R allowing of this motion of the coupling-frame around the coupling-bar, as is readily seen.

The hoisting-lever 6 is pivoted to the side plate 4, and has the segment 12 at its lower ends, to which is attached the chain 13, which passes over the pulley 51 to the couplingframe, to which it is attached.

The ratchet-segment 11 is secured on the side plate 4, and the pawl 10 is pivoted on lever 6, and engages with the ratchetsegment 11 to hold said lever in any desired position.

The pawl 10 has attached to it the wire 8, (see Fig. 2,) which lies alongside the lever 6, and is coiled around the upper end of said lever into a handle, 7, which is grasped by the driver when the lever 6 is to be moved, so that by sliding his hand up or down he can release or engage the pawl 10 with the ratchet-segment 11, as is readily seen.

- The corrugated seat-rods o v are secured on the machine-frame, as shown, and the seat W is swung on them by the springs X X and open hooks w 10, so that it can be readily shifted to balance the machine, or can be readily removed, if desired.

The finger-bar is attached to the couplingframe by means of the pivoted hinge-arm '1, which is secured to the frame by the bolt q, and by means of the pivoted hinge-bolt l, which is secured in the eye 70, as shown in Figs. 1, 13, and 14, or by the arm S, which is riveted to the frame, as shown in Fig. 10, the pivot hinge-bolt lbeing used when it is desirable to have the finger-bar so arranged as to be folded up in the position indicated by dotted lines in Fig. 1, which folding is effected by removing the pin 19, which unites the finger-bar to the hinge-arm T, and then turning the finger-bar first into an erect position, and then turning it forward around the boltl as a pivot, and the stiff arnrS being used when only the folded position of fingerbar (indicated by dotted linesin Fig. 2) is required.

The pivoted hinge-arm T is held in position by the crank-screw 1', which is made in the crank form shown in Fig. 12, so as to be conveniently removed or inserted, and in the tapering form on the threaded portion, .as shown, so as to bind itself in the hole in the bar M and arm T, and be thus prevented from working loose.

By removing the screw 1" thearm Tand fingerbar may be swung around, indicated by dotted lines in Fig. 13, for convenience, in transporting a machine when the platform is combined with finger-bar in reaping.

The heel-shoe Z consists of the wroughtiron or steel .plate Z, which is bent upat each end, and has combined with it the castin gs. f

and g, as shown in Fig. 4, so as to form the hinge-sockets for the arm T and bolt 1 orarm S, to which it is secured by pins or bolts 12 n, as shown in Fig. 13.

The rear end of casting f and the plate h, which is secured on the finger-bar Uin the shoe Z, form a guard for the shank of .the knifebar 67, which knife-bar is operated by. pitman 2, attached to the crank-pin y on the. crankwheel as on the crank-shaft 5 in .an ordinary manner. 4

Where a wheel is desired at the heelof the finger-bar the arm 64 is cast on the rear part of the shoe Z, as shown in Fig. 11,.and the wheel 15 is secured on said arm by an axle-pin, 'u, as shown. 7

The grain-shoe Y has the arm a. at .its rear end, 011 which is secured the wheelb by means of the axle-pin e, as shown in Fig. 3; v and the tracker-rods 0 c are secured in position by insertin g their bent ends into holesinthe upright fluke of the shoe, and then dropping them between said fluke and the standard (I.

The fingers V V are secured on thefingerbar U in an ordinary manner.
